Singer Avril Lavigne has created a range of edgy nail polish designs for top beauty company Sally Hansen.

The Sk8er Boi hit-maker, who already has a fragrance brand and clothing line Abbey Dawn, has extended her fashion empire by releasing a limited-edition collection of self-adhesive nail strips for Sally Hansen's Salon Effects.

She tells Women's Wear Daily, "This is pretty much the coolest thing... I'm a really visual person; I like creating, and I love to have fun with colors. I think this offers self-expression, and it's a really smart, versatile way to show your style. I think my fans will really like it, because it's easy and simple and fun.

"I was really excited... since they're super quick. You clean your nails, peel the strips and apply them, file and go. I'm superfast at it, so it takes me like five minutes to do my nails. And it's super cool because the designs that I came up with are my personal style and vibe - they're rock 'n' roll and fun and bright and colorful. You have sparkles and little stars - they are cute."

"For me, I'll be flying on a plane and be like, 'S**t, I need to do my nails.' I can do these on a plane; I've done them in the car."
